Dating vs carbon

Tests indicate that the earth has still not reached equilibrium.There is more C-14 in the atmosphere now than there was 40 years ago.They do not know that the amount of carbon-14 in the atmosphere is constant. In addition to the above assumptions, dating methods are all subject to the geologic column date to verify their accuracy.Present testing shows the amount of C-14 in the atmosphere has been increasing since it was first measured in the 1950's. Etna, Sicily (AD 1972) gave K-AR age of 350,000 years old. If a date obtained by radiometric dating does not match the assumed age from the geologic column the radiometric date will be rejected. 30 "The lower leg of the Fairbanks Creek mammoth had a radiocarbon age of 15,380 RCY, while its skin and flesh were 21,300 RCY. 124 The two Colorado Creek mammoths had radiocarbon ages of 22,850 670 and 16,150 230 years respectively." --In the Beginning Walt Brown p.Since so many wrong dates are found, how would we know which dates are "correct? Then skull #KNM-ER 1470 was found (in 1972) under the KBS tuff by Richard Leakey. 1999 Lava from the 1801 Hawaiian volcano eruption gave a K-Ar date of 1.6 Million years old. B., 1969 40Ar/36Ar analysis of historic lava flows. There are about 7 or 8 radioactive elements that are used today to try to date objects. A hominid species assumed to be an ancestor of Homo sapiens, erectus was thought to have vanished some 250,000 years ago. "Structure, metamorphism, sedimentary reworking, and other complications have to be considered." For years the KBS tuff, named for Kay Behrensmeyer, was dated using Potassium Argon (K-Ar) at 212-230 Million years. It looks like modern humans but was dated at 2.9 million years old. Etna, Sicily (122 BC) gave K-AR age of 250,000 years old. B., 1969 40Ar/36Ar analysis of historic lava flows. Each one has a different half-life and a different range of ages it is supposed to be used for. But even though he used two different dating methods, Swisher kept making the same startling find: the bones were 53,000 years old at most and possibly no more than 27,000 years— a stretch of time contemporaneous with modern humans." --Kaufman, Leslie, "Did a Third Human Species Live Among Us? Radiometric dating would not have been feasible if the geologic column had not been erected first." --O’Rourke, J.At some point you would be putting it in and it would be leaking out at the same rate.You will not be able to fill the barrel past this point of equilibrium.

This also means that plants and animals that lived in the past had less C-14 in them than do plants and animals today.In order to find the length of time since the candle was lit we would be forced to make some assumptions.We would, obviously, have to assume that the candle has always burned at the same rate, and assumes an initial height of the candle. Similarly, scientists do not know that the carbon-14 decay rate has been constant.A very small percentage of the carbon plants take in is radioactive C-14.When a plant or animal dies it stops taking in air and food so it should not be able to get any new C-14.One gram of carbon from living plant material causes a Geiger counter to click 16 times per minute as the C-14 decays.
